prop-1 / RC-4 question

[Mark R]

Hi, I am trying to hook up three RC-4 boards to my prop-1 controller to run a light show. Where do I hook the cables at on the prop-1 and where do they connect on the RC-4 boards to link them all together?

This illustration should help:




Notes:
-- remove the Prop-1's ULN2803A; replace with ULN2003A as shown (leave top socket pins open)
-- each accessory has two sets of serial headers; either can be in or out (they're the same electrically)
-- when mixing the RC-4 with other devices, the RC-4(s) must come first in the chain as they get power from the Prop-1 or Prop-2
-- for the Prop-1 with 2400 baud, remove the Baud (sometimes labeled B/R) jumper from all devices
-- when using multiple devices of the same type (e.g., four RC-4s) you must set the address jumpers differently on each device of the same type

Address	A1	A0
%00 (0)	out	out
%01 (1)	out	in
%10 (2)	in	out
%11 (3)	in	in
